I Found a Production Mistake on the Spectrometer!

This Bomem DA-3 Fourier Transform Infrared Spectrometer is one of my all time favorite machines in the room. It just has so many amazing things to teach me, and boy howdy do we go on a ride in this one. We discover a production fault with the machine, we discover I’m a bit of a dummy, and we get to play a lot with the laser!
